Description
Technical field
The utility model relates to the pressure testing device at well mouth of petroleum industry oil-water well, particularly oil-water well blowout preventer set pressure testing device at well mouth, salable well head, completes the pressure testing construction of well head blowout preventer set.
Background technology
In offshore oil exploration and exploitation process, the well control work of oil-water well is the most important thing of whole mouth well construction, if it is out of control that well head occurs, the personnel's injury caused, equipment loss, environmental protection accident and the negative effect brought are difficult to estimate.And offshore field generally adopts safety valve control oil pipe, cable-passing packer to control the mode of production of sleeve pipe at present, its control system liquid controling pipe line used, cable cause the control device on ground through completion seat in the hanger of well head, ensure that the safety in production of oil-water well to a certain extent.But simultaneously, owing to just utilizing single pressure testing blind plugging to preventer connecting portion pressure testing more than well head four-way at present, fail effectively to protect the position of passing through on hanger, cause the cable penetration hole on hanger to become the weak spot of well-control blowout prevention device group pressure testing when later stage job execution.Often occur in construction causing the cable at cable penetration hole place to fall in well because pressure test pressure is high, the normal pressure testing of blowout preventer set cannot be realized.The jackscrew individual part of the old Jing Sitongchu of part is aging in addition, also easily causes during pressure testing and stings, leaks, cannot normally pressure testing.Production scene needs a kind of pressure testing device of wellhead blowout preventor group to solve the problem.
Summary of the invention
The purpose of this utility model is to provide oil-water well blowout preventer set pressure testing device at well mouth, carries out pressure testing to blowout preventer set by design standard, eliminates the potential safety hazard of blowout preventer set, guarantees the well control safety of construction well between operational period.
Technical solution of the present utility model is: oil-water well blowout preventer set pressure testing device at well mouth comprises base, gland, pressure testing plug and fastening box cupling, gland is provided with pressure testing hole, pressure testing plug is provided with seepage flow hole, between base and gland, packing element is housed, pressure testing plug is set on base and is connected with fastening box cupling with in gland.
Remarkable result of the present utility model is: this device is connected to former Jing Xuanguaqichu, utilizes fastening box cupling to extrude gland and packing element, the weakness such as salable hanger cable penetration place, liquid controling pipe line junction and well head four-way jackscrew.Now enter pressure testing drilling rod down again, close preventer, by platform three cylinder pump to pressure testing drilling rod pumping liquid, the annular space between pressure testing drilling rod and preventer is entered by the seepage flow hole of this device and pressure testing hole, thus at the construction field (site) just can according to design standard required pressure, complete the pressure testing of blowout preventer set rated pressure, ensure the use safety of blowout preventer set, avoid the generation of well head incontrollable accidents.After pressure testing terminates, by carry pressure testing drilling rod, utilize the lifting baffle ring of pressure testing plug to take the utility model out of.This apparatus structure is simple, reliable operation, changes the deficiency that current testing pressure of well head method exists, makes blowout preventer set reach the requirement of well control design safety standard, for the well control safety construction of oil-water well is given security, has significant effect.
